Are you looking to expand your laboratory’s testing capabilities? Gentian’s Retinol-Binding Protein (RBP) Immunoassay offers a quantitative measurement of RBP on routine chemistry analysers, supporting diagnostic insights across vitamin A status, nutrition, renal health, and diabetes.
RBP is particularly relevant in nutritional screening, monitoring of kidney tubular function, and metabolic disease evaluation:
Growing focus on nutritional assessment
Increased metabolic disease burden
Need for rapid, scalable biomarkers
Retinol-Binding Protein (RBP) is a key transport protein for vitamin A (retinol) in the bloodstream. Synthesized in the liver, RBP binds to retinol before entering circulation. After retinol delivery, RBP is filtered by the kidneys and nearly fully reabsorbed by the proximal renal tubule.1,2
RBP levels are relatively stable in healthy individuals, but fluctuations may signal underlying health conditions, including:
Gentian’s turbidimetric RBP assay is designed for automated, high-throughput clinical chemistry analysers, enabling seamless integration into routine workflows.
The assay boasts high precision with a coefficient of variation (CV) below 5% and a limit of quantification (LoQ) at 7.81 mg/L. The measuring range extends from 7.8 to 139 mg/L, making it suitable for various clinical needs.
